Griffco Valve, based in Amherst, New York, has introduced its new line of pulsation dampeners to enhance the performance of chemical feed systems.
The addition of a Griffco pulsation dampener to a pumping system will reduce harmful shock waves and deliver continuous chemical dosage at the injection point, according to the company.
In an initial release, nine volumetric sizes are offered ranging from 6.0 to 125.0 cubic inches with a dampening effect of ±2.5%, with larger sizes to be released at a later date.
An interactive pulsation dampener sizing calculator on Griffco’s website enables operators to select the correct size unit based on their volume per stroke, mean system pressure, type of pump, type of gas, and desired dampening effect.
The new Griffco pulsation dampeners have maximum pressure ratings of 17 bar for metallic models and 10 bar for plastic models operating at up to 21°C.
Connection sizes include 1/2”, 3/4”, and 1” (DN 15, DN 20, and DN 25) in NPT, BSPT, Socket, Union, or Flange connections.
Gauge port sizes are offered in 1/8”, 1/4”, and 1/2” (DN 6, DN 10, and DN 15).
Manufactured in the US, the dampeners feature a choice of moulded Noryl, PP, PVDF, or 316 stainless steel construction.
The diaphragm is supplied in EPDM standard, Viton, or Hypalon optional, and the gauge and charging valve materials are brass (standard) and 316 stainless steel (optional).
